In order to be able to reimburse my motherland in the early days of the founding of the People's Republic of China, I refused the various attractive conditions of Country M, including an annual salary of tens of millions, high-level positions, etc. Even though my mentor persuaded me many times, I did not change my determination to return to my country. Just because I am a time traveler, I was a scientist of my motherland in my last life. I am familiar with the history of the early days of the founding of the country, and I must contribute all my strength to the future of our motherland.
